Mid-level clouds. Lets start with altocumulus clouds.
These have several patchy white or gray layers, seemingly comprised of numerous small rows of fluffy ripples. They’re lower than cirrus clouds, but still quite high. Consisting of liquid water, they seldom produce rain.
These predict fair weather.
Altostratus clouds are gray or blue-gray clouds made of ice crytals and water droplets. These usually cover the whole sky.
Be prepared for continuous rain or snow.
Nimbostratus clouds are dark, gray clouds. They seem to fade into falling rain or snow. So thick, they often block sunlight.
Gloomy with continuous rain or snow.
Finally, the high clouds.
Cirrus clouds are delicate, feathery clouds composed of mostly ice crystals. Wind currents make for their wispy shape, twisting and spreading ice crystals into strands.
A change is on the way!
Cirrostratus clouds are thin, white clouds covering the entire sky like a veil. Cirrostratus are seen mostly in the winter and can appear as a halo around the sun or moon.
Rain or snow will arrive within 24 hours!
Lastly, cirrocumulus clouds.
Thin, sometimes patchy, sheet-like. They look full of ripples or like they’re made of small grains.
Fair, but cold. In the tropics, these could be a sign of an approaching hurricane.
Watching these clouds, the GOES-16 satellite. It sees detailed changes in cloud-tops, helping assess potential size and severity of a storm before it reaches it’s peak!
